Use your AAdvantage miles to upgrade on flights marketed and operated by American Airlines or American Eagle for yourself or anyone you designate.

Upgrades are valid to the next cabin of service* and are valid for a single one-way trip with a maximum of three segments. Upgrades are subject to capacity controls. Excluding award tickets, the following eligible fare types can be upgraded:

Discount Economy with published fares booked in H,K,M,L,W,V,G,Q,N,O,S and

Military or Government fares booked in Y

Full-Fare Economy with published fares booked in Y

Discount Premium Economy with published fares booked in P

Full-Fare Premium Economy with published fares booked in W

Discount Business with published fares booked in I

Full-Fare Business with published fares booked in J, D or R

Basic Economy fares booked in B are not upgradable

*E.g. Economy to Business, Business to three class First. At this time Premium Economy is treated as Economy for upgrade purposes.

NOTE: The most expensive fare classes, full fare Economy Y, full fare Premium Economy W, and full fare Business J, may be upgraded without copay and at a lower cost in miles. See here.

Taxes and carrier-imposed fees:

Co-payment is non-refundable and inclusive of U.S. excise tax where applicable.

Mileage upgrade award tickets are subject to applicable taxes and security fees and may incur additional taxes as a result of upgrading to a higher class cabin (includes higher U.K. Air Passenger Duty If Flight originates in the UK or is a connecting flight with a connection time of 24:00 or more)..)

Upgrading from Economy Class to Business Class or First Class may result in additional premium cabin taxes and carrier-imposed fees, including but not limited to flights originating in Great Britain and France.

If the ticket is priced in USD, the additional taxes and carrier-imposed fees will be converted to USD at the time of ticketing.

Miles and copay upgrades are to the next available cabin of service, are based on inventory being available, usable on AA marketed and operated flights (not codeshares operated by other airlines, not on other airlines' prime flights - BA and IB allow miles upgrades with AA miles but are very different and therefore not treated here).

If the required inventory exists, they can be booked positively (i.e. upgraded immediately); if not, the request is wait listed. Wait list clearance is by status (EXP highest, no status lowest), and within status priority is by rolling 12 month EQD spend. Elites can have one traveling companion on the same PNR "borrow" their status for upgrade wait list purposes, until the request goes to the airport list, where you may want to assure your travel companion continues to hold your “borrowed” status for upgrade purposes.

Frequently Asked Questions / FAQ:

Q. It says the upgrade fees are nonrefundable. Do I lose my miles and money if I'm not upgraded?

If your upgrade request does not go through, miles and copay are in fact refunded.

Q. If I am waitlisted, in what priority order are upgrades processed?

Upgrades are processed first by AAdvantage status tier, secondarily by type of upgrade, thirdly by the previous rolling 12 month EQD spend.

Q. Which has higher priority if all other preceding factors are the same? An upgraded with miles + copay, or an upgraded with SWU?

They have equal priority. A few reports state copay + upgrade have been given priority at some overseas stations.

Q. How soon will I know if my upgrade came through?

It can happen anytime inventory opens, from the time you book until the time you board. (Your request, including date and time of request, should carry over automatically to the airport list.)

Q. How soon will I know if my upgrade came through?

It can happen anytime inventory opens, from the time you book until the time you board. (Your request, including date and time of request, should carry over automatically to the airport list.)

Q. How many flights can I upgrade with a single miles plus copay upgrade?

You may (assuming available inventory) upgrade up to three segments on the same ticketed itinerary (e.g. LHR-ORD-MIA-EZE, as long as they are on the same PNR).

Q. Can I look at AAnytime or MileSAAver award space to determine upgrade availability?

No. MileSAAver availability may be a good indication upgrade space may become available, but SAAver and upgrade inventories are separate.

Q. What fare inventory do I need to upgrade?

You need available "C" inventory to upgrade to two class domestic First and three class Business, "A" to three class First. These are not shown on aa.com, but some services (e.g. ExpertFlyer) do show them.

Q. I'm Executive Platinum. If I purchase an upgrade for someone without status, will they "borrow" my status for upgrade purposes?

They will if they are flying as your single traveling companion on the same flights. Otherwise, their status will determine their position on the upgrade wait list. This "borrowed" status was previously lost once the flight has gone to airport control; it doesn’t now, but it pays to check and see if it has been mismanaged by software - it can be restored when it has passed to airport control.

Q. Which miles earning and fare conditions will apply to my upgraded flights?

You will earn miles (award miles -- RDM -- and EQM) and EQ Dollars credit as determined by your originally purchased fare, and the applicable fare rules will also be determined by your originally purchased fare.

So, if you've requested a 500-mile upgrade, your on-line AA flight info reflects that, as does the app. What if you're waitlisted for a miles+copay upgrade? I supposedly am but don't see that reflected in either place. Should I be concerned, or does that just not get displayed for some unfortunate reason?

I have a three-segment domestic flight for 2 pax, booked in discount Y, and wanting to upgrade with miles+copay. My understanding is that I need A availability. Current situation per ExpertFlyer is:

Segment 1: A7
Segment 2: A1
Segment 3: A4

Can I go ahead and process miles+copay upgrade (for both passengers) and confirm segment 1 and 3 for both of us, segment 2 for one of us, and waitlist segment 2 for the other? If yes, can I then call back in later if more A availability opens up on segment 2 and get the upgrade processed?

I looked on Flyertalk for other stories in which a flyer had a confirmed miles/copay upgrade, and then ultimately sat in economy and had trouble getting the copay refunded. Couldn't find one, so sharing my experience:

Nov: I'd applied and cleared a miles/copay upgrade for EWR-DFW-LAX flights in Dec. (Opted for this routing instead of my usual FK-LAX in order to try AA's 787, which was scheduled to operate the DFW-LAX segment)

Mid Dec (day of flight): 1st segment is delayed such that if I took it, I'd get stranded overnight in DFW. So I'm rerouted EWR-PHX-LAX -- in economy, due to full first class cabins.

Late December: Seeing my miles/copay hadn't been refunded automatically, I called the EXP line and requested a refund. The 15k miles are refunded, but told that to get the $75 I need to request a refund online with accounting. I do that. One month later, the request is denied without explanation.

Jan - mid March: I call the EXP line 2 more times and sent AA customer service 11 emails requesting the refund. One response was to send the flight details, which I did. Two more responses were to send the same flight details I'd already supplied. Several other responses seemed to completely misunderstand my request and just apologized for the delay. Several were never responded to.

A few days ago: Received the $75 refund, over 3 months after the flight. Truly a Phyrric victory.

Does anyone know how mileage upgrades work when transiting through North America? Flying LHR-JFK-BOS-LAX-SYD. I am assuming I would have to use two upgrades plus copays?

1 TATL upgrade award + 1 TPAC upgrade award. If either of them clear, you can have the domestic legs bundled with them. Or, just do a domestic upgrade and enjoy the transcontinental in F. If you had an evip, you could do up to 3 of the segments and skip the short hopper.

That type of upgrade is good for 3 segments, so definitely LHR-JFK-BOS-LAX. I'm not sure though whether you can choose which segments, for example, could you skip JFK-BOS and use the upgrade on LAX-SYD?

Firstly, it is a 'space available' upgrade so you may not be able to do it at the time you book, or indeed at any point at all, but you can wait-list if it is not available and if you get lucky it happens, if not you travel in coach (but do not pay the miles or the co-pay).

If you are upgraded you will earn based on the original class of travel, not the upgraded class.

Yes, you are allowed to call and make a request. You probably will be charge if you book your seats over the phone. A better option is to book through AA.com and then call for an upgrade. You will earn EQMs based on the discount economy booking.
